Given a square in the middle of the graphics window with these coordinates:

(-1,1)       (1,1)
      -------
      |     |
      |	    |
      |	    |
      -------
(-1,-1)      (1,-1)

write code that asks the user to click anywhere on the window. If they click
outside the square, draw the Point where they clicked. If they clicked inside
the square, output "All Done" at the top of the window.

Solution:

Point click = cwin.get_mouse("Click anywhere");

if (click.get_x() < 1 && click.get_x() > -1 &&
    click.get_y() < 1 && click.get_y() > -1)
{
   cwin << Message(Point(-9,9), "All Done");
}
else
{
   cwin << click;
}

Bonus (double points if correct):

What is the value of the following expressions?
